New discoveries made at the Klasies River Cave in South Africa's southern Cape, where charred food remains from hearths were found, provide the first archaeological evidence that anatomically modern humans were roasting and eating plant starches, such as those from tubers and rhizomes, as early as 120,000 years ago.

Scientists with the Universidad San Francisco de Quito and WCS Ecuador Program publishing in the journal BioTropica say that subsistence hunting in Neotropical rain forests—the mainstay of local people as a source of protein and a direct connection to these ecosystems—is in jeopardy from a variety of factors.

Even as warnings of climate catastrophe and calls for greener economies grow ever louder, the world is still spending hundreds of billions of dollars every year to subsidise the fossil fuels that are causing the planet to overheat.

A new "demographic inference" tool developed by academics can make predictions based solely on the information in a person's social media profile (i.e. screen name, biography, profile photo, and name). The tool—which works in 32 languages—could pave the way for views expressed on social media to be factored in to popular survey methods.

"By ecology, we understand the whole science of the organism's relationship with the surrounding outside world, which includes in a broader sense all 'existential conditions'. These are partly organic and partly inorganic in nature; both the former and the latter are, as we have previously shown, of utmost importance for the form of the organisms, because they force them to adapt to them."

For four weeks, 20 healthy volunteers checked into a research center hospital and were served a variety of tempting meals: cinnamon french toast, stir-fry beef with broccoli and onions, turkey quesadillas and shrimp scampi. Researchers scrutinized everything that was eaten and came away with the first hard evidence to support a long-held suspicion: Heavily processed foods could be a leading factor in America's obesity epidemic.
